Improvement in gang-plows

IMPRov'EMENT vIN GANG-Hows.

The Schedule referred to ln'these Letten Patent and part of the same.

To all whom tt may c omwm:L

Be it known that I, JOHNMURBY, of Silveyville', county of Solano and State of California, have invented certain new and useful Improvements in Gang-Plows; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing and letters marked thereon.

My invention relates vto that class of gang-plows which has the plows attached to aI hinged frame, which is elevated by suitable mechanism when it is desired tovlift the plows; and consists in certain details of construction, which will be fully described hereinafter.

In 'the drawing- Figure l is a bottom view.

Figure 2 is a'side elevation.

To enable others skilled in the art or science to make and use my invention, I will proceed to describe fully its construction and operation.V

A represents the sides ot' the frame to which the plows are attached, and which I construct of at iron bars placed edgewise, with suitable Wood braces B B' between to strengthen the frame and prevent it from springing.

The ends of these bars are bent downward, and are' jointed to arms C OV by the rod D. I, construct my axle in one piece of iron, and the arms which connect with the frame are clipt to it.

The clip E also holds the arms FF, which supports a double brace-rod, G, which passes through a horizontal balance-beam, H. Thisbeam is pivoted tothe supports below the drivers box by a pin.

The opposite end of the lever is connected to the brace B of the frame by a double hat link, I, with holes for raising and lowering the rear end of theA plowframe.

In the center ofthe axle I make a journal, J, which turns in the end of the draft-pole.

At the right 'ot' the drivers seat is attached to the axle a lever, K, and by forcin'g this leverdownfthe axle turnsl in the hubs of the wheels nearly half way round and draws down the connecting-rod attached to \the end of the balance-beam and raises thewhole gang and frame, and still maintaining. them in a horizontal position, while the arms O Q are nearly in a' vertical position, and the balance-beam will be at an. angle of about forty-ve degrees.

rlhrongh the raising and loweringv lever passes a segmental arm, k', with pin-holes for holding the plows at the desired height.

For turning the plows to or from land the hounds L L are provided with slots where they connect with the pole, which admits of each being lmoved backward or forward by unloosening the screw-bolts M M, and by lengtheningor shortening the connection of either lthe frameis given a greater or lesser inclination to the right or left. v

rlhe hounds I also construct of iron, the opposite ends of which are simply provided with holes and are sprung ,upon the axle against the shoulders, being separated from the hubs of vthewheels by a Washer.

I construct the furrow-wheels of my plow larger than that of tl1e1land-wheel,and both wheels may be made of cast-iron. y y A My plows have atiron standards, and are attached rigidly to the iron frame, so that strength and dura-4 bility is imparted to the whole machine.

By raising and dropping the latlink at the end of the balance-beam the whole frame may be folded over against the'drivers seat for transportation.

In constructing my gang-plow it will be observed that but a small portion of it is made of wood, and the machine willnot be materially inj ured'by exposure to'the weather, whichis considered great desideratnm in sections ofthe country where suitable buildings for storing farming vimplements 'are rarely ever erected.

Having thus described my invention,

What I claim, and desire to secure by Letters Pat# ent, is-

The arrangement`- of the frame A, bars C, axle E, lever K, balance-beam H, connectingrod'G, and link I, as described, for the purpose set forth.

4In testimony whereofI havev hereunto set my hand `and seal.v
